RE: Alarm to connect to CBus (excluding Comfort)

["Mike Griffiths" <mike@xxxxxxxxxxxx>]

The main difference is in the connection
With C-bus if you cut the cable the PIR stops working and possibly the
whole C-bus network !
With an alarm system if the cable gets cut the alarm goes off as the
alarm system is still working

Thanks Kevin.
I understand that the CBus PIRs have a control rather than a security
characteristic, will do some digging as to what that actually means.
Is it fair to say that these 'system's that we put together will never
satisfy insurance required standards - to get discounts?
Take your point about separate alarm system - just want to explore
Cheers
